Title: Film cassette with film exposure status indicator
Inventor: PAGANO DANIEL M
IPC: G03C3/00
Filed: 1990-10-29
Abstract: FILM CASSETTE WITH FILM EXPOSURE STATUS INDICATOR              ABSTRACT OF THE EXPOSURE         A film cassette comprises a film spool supported inside a lighttight cassette shell for rotation to thrust a filmstrip coiled about the spool automatically to the exterior of the shell, and a film exposure status indicator supported for movement with respect to the shell from an unexposed position for providing a visible indication that the filmstrip is unexposed to an exposed position for providing a visible indication that the filmstrip is exposed.  According to the invention, the shell and the status indicator include mutually engagable means for locking the indicator in its unexposed position to prevent the indicator from being manually moved to its exposed position but which can be disengaged by a suitable device in a camera, for example, to unlock the indicator to permit the indicator to be mechanically moved to the exposed position.

Title: Ambient radiant energy concentrator
Inventor: HORSLEY PETER B
IPC: G02B5/08
Filed: 1991-01-03
Abstract: ABSTRACT   It is common in devices for collecting and concentrating radiant energy to focus the rays to a small region. To be effective, such devices must face towards the source of the energy, usually the sun. I have found that by diverging the rays instead of converging them, the device can then face any direction, and does not need the sun as a source of energy. This factor gives my device the advantage of continuing to function whether or not the sun is shining. My device continues to function at night and in cool weather. The method consists of taking a bundle of rays that are converging on a point, and of reducing the angle of the convergence. If the rays are squeezed into one half the angle, for example, the concentration of radiation isdoubled. In my device the angle of convergence is reduced to a narrow line, thereby concentrating the radiant energy entering the device by a hundredfold or more. The receiving element is a boiler tube, from which the concentrated energy can be directed to a turbine for conversion to useful rotary energy.

Inventor: HAYS ERIC L
IPC: H01F27/245
Filed: 1991-09-23
Abstract: A transformer core and method of assembling the core which utilizes a plurality of two types of generally E-shaped laminations, type A and type B, each having two legs extending approximately the same distance and an outer third leg extending a distance substantially greater than the distance extended by the other two legs, thereby providing an extending outer leg portion on both laminations. The laminations are formed by stacking a number of core members, two of which are cut from a rectangular section of electrical steel. The type A core members and laminations are provided with a notch and an indentation extending from the bottom perimeter of the base. The type A and type B laminations are alternately positioned on stacking shims with the extending leg portion of all type A laminations at one side and the extending leg portion of all type B laminations on the opposite side. The notch and indentations cooperate with the shims to provide channels between the extending middle legs of the type B laminations because the dimensions of the base and middle leg of type A and type B laminations are otherwise the same. A separate transformer coil is placed over each of the three core legs. A plurality of I-shaped laminations are then positioned between the extending outer leg portions of the E-shaped laminations, are supported on the middle legs and extend to the opposite extending outer leg portions.       I-shaped laminations which are positioned within the channels are inserted first thereby providing additional guidance fot positioning the rest of the I-shaped laminations between those that are received in the channels.

Title: Method of driving a matrix-type liquid crystal display device
Inventor: ONO JYUNICHI
IPC: G09G3/36
Filed: 1991-12-18
Abstract: A method of driving a matrix-type liquid crystal display device utilizes a liquid crystal layer sandwiched between a plurality of scanning electrodes and a plurality of signal electrodes extending generally perpendicular to the scanning electrodes.  A display is erased by bringing it into either a light transmitting state or a light scattering state, and then selectively writing pixels at each intersection between the scanning and signal electrodes to reverse their optical state. The pixels are retained in their optical states after the writing step.  During the erasing step, all of the pixels are subjected to a high alternating voltage or a high direct current voltage.  During the writing step, the scanning electrodes are line-sequentially selected and the signal electrodes receive a signal of a waveform effective to apply a high voltage to those pixels desired to be reversed and a low voltage to those the pixels desired to be unchanged.  During the retaining step, a low alternating voltage or a low direct current voltage is applied to all of the pixels.
